3,4Z,fi%3 Fatentecl July 3, 1952 3,042,683 PHTHALOCYANINE COLOURING MATTERS Harold Thompson Howard and Christopher David Marrable, Manchester, England, assignors to Imperial Chemical Industries Limited, London, England, a corporation of Great Britain No Drawing. Filed June 17, 1960, Ser. No. 36,739 Claims priority, application Great Britain July 2, 1959 Claims. (Cl. 260-3145) This invention relates to phthalocyanine colouring matters.
It is known to colour cellulose acetate rayon by a mass colouration process in which a suitable colouring matter is incorporated with a solution of cellulose acetate in acetone and the mixture is then spun into filaments.
The present invention relates to new colouring matters of the phthalocyanine series which are soluble in acetone and are suitable for use in the mass colouration of cellulose acetate rayon.
According to the invention we provide new colouring matters of the formula wherein Pc stands for the residue of a stable metal phthalocyanine colouring matter, -X stands for CH or 40 R stands for a lower alkylene radical, R stands for a lower alkyl or an aryl radical, R stands for hydrogen or a lower alkyl radical or for the group R .O.CO.R where R, is a lower alkylene radical,-
and n is any number from 2 to 8.
As examples of stable metal phthalocyanine colouring matters there may be mentioned the phthalocyanines of copper, cobalt, nickel, iron, aluminum and chromium, and their derivatives in which the phthalocyanine nucleus is substituted, for example by halogen atoms such as chlorine, or aryl radicals such as phenyl and tolyl which may be attached directly to the phthalocyanine nucleus or through a linking atom or group for example a S, --CO- or SO NH- group. The radical X- in the above formula may be attached directly to the phthalocyanine nucleus or to a pendant aryl radical which itself is attached directly or through a linking atom or group to the phthalocyanine nucleus.
Those new colouring matters of the invention in which X stands for SO; may also contain not more than one sulphonic acid group, either attached directly to the ,phthalocyam'ne nucleus or to a pendant aryl radical.
As examples of lower alkylene radicals which may be represented by R and R there may be mentioned ethylene, 2-ethy1ethylene and Z-n-propylethylene. As examples of lower alkyl or aryl radicals which may be represented by R there may be mentioned methyl, ethyl,-
phenyl and chlorophenyl and as examples of lower alkyl radicals which may be represented by R there may be mentioned methyl and ethyl As specific examples of the colouring matters of our invention there may be mentioned copper di, triand tetra-[di-(B acetoxyethyl) aminomethyHphthalocyanine, copper triand tetra-[di-(fi-acetoxyethyl)arninomethyl] tetra-(tolylmercapto)phthalocyanine, copper di, tri-, and
tetra-[di (B propionyloxyethyl)aminomethyHphthalocyanine, copper di, triand tetra-[di-(B-benzoyloxyethyl) aminomethyflphthalocyanine, copper tetra-[di (5 acetoxyethyl aminomethyl] tetraphenylphthalocyanine copper octa [di (B acetoxyethyl)aminomethyl1octaphenylphthalocyanine, copper triand tetra-(fl-acetoxyethylsulphamyl)phthalocyanine, copper triand tetra-[di-(B-acetoxyethyl) sulphamyflphthalocyanine, copper tetra [N- ethyl-N (,8 7 acetoxyethyl)sulphamyjphthalocyanine and copper tri-[N-(fi-acetoxyethyl) N (B acetoxypentyl) sulphamyHphthalocyanine, nickel and cobalt tri-(B-acetoxyethylsulphamyl)phthalocyanine and copper tetra-4- chloro-tri- B-acetoxyethyl) sulphamylphthalo cyanine.
According to a further feature of the invention we provide a process for the manufacture of the new colouring matters as hereinbefore defined which comprises treating a hydroxy compound of the formula with the anhydride or chloride of a carboxylic acid of the formula R COOH wherein Pc, X, and R have the meanings previously stated, and R stands for hydrogen or a lower alkyl radical or for the group -R OH wherein R is a lower alkylene radical.
The process of the reaction may conveniently be carried out by heating, for example to the boiling point, a suspension of the hydroxy compound in the acid anhydride until a solution is obtained. This usually requires between 1 and 4 hours. To isolate the product the solution may, for example, be diluted with about 10 times its volume of cold water and the mixture neutralised by addition of a dilute alkali such as sodium carbonate. The solid so precipitated may then be isolated by filtering, washing and drying. If desired the product may be purified by dissolving it in acetone, filtering from insoluble matter and evaporating the acetone solution to dryness.
Hydroxy compounds suitable for use in the process of the invention may be obtained by reaction of a chloro compound of the formula PcX-Ol wherein Po and X have the meanings already stated with the appropriate hydroxyamino compound. Thus the hydroxy compounds in which -X stands for CH may be obtained from chloromethyl phthalocyanines and the hydroxy compounds in which X stands for SO may be obtained from phthalocyanine sulphonyl chlorides. Reaction of a chloro compound of the above formula wherein X stands for SO with a hydroxyamino compound may result in the formation of a product which contains sulphonic acid groups in addition to substituted sulphonamide groups. Such products are nevertheless suitable for use in the process of the invention, provided that they do not contain more than one sulphonic acid group.
According to a further feature of the invention we provide an alternative process for the manufacture of the new colouring matters as hereinbefore defined which comprises treating a halogeno compound of the formula Pcl-X-halthe alternative process of the invention there may be mentioned 13-acetoxyethylamine and di(fi-acetoxyethyl)amine.
The new colouring matters of the invention are suitable for use in the colouration of. plastics and lacquers,
and being readily and completely soluble in acetone they are especially suitable for use in the mass colouration of cellulose acetate rayon, giving blue to green shades of high fastness to light and to wet treatments.
The new colouring matters in which Pc stands for cop- V per phthalocyanine form a preferred feature of the in- 7 Example 1 5 parts of a mixture of copper diand tri-[di-(B-hydroxyethyD-aminomethyl]phthalocyanine is stirred with 25 parts of acetic anhydride and boiled under reflux for 1 hour.
